=have invent'ed certain new and useful Improvements nDumping-Cars, of which the.

and exact specifiollowing is a full, clear,

I This invention relates todumping cars, and has particular reference to reversible actuating mechanism for cinder cars or the "car body is mounted to be dumped in oppolike, wherein a tilting'and, laterally movable.

site directibns'from'a 'eentral upright poing car wherein the motor may be discon- "sition; I v V More, particularly; the invention comprises a'power actuated trunnion-supported dump .nectedfrom the carbody for the purpose of icvers ing the .operation,-that is to say, when .it 1S11655.1?(1v to. dump theicar body on one side instead of on the other. I According to 5 this" invention. there are preferably provided between the-inotor'and the "trunnion of the car, bodyfadjustable crank connections adi'usted' from one position to another according to. the side on which the carbody is. to

be operated, whereby the motor has a greater travel than the car body and the power is ,aplied atgreaterleveragefurther feature of the inventionc'omprises fai conibined hydro-pnuematic apparatus for supplying? the actuating pressure whereby the motoris actually moved by hydra11lic pressurdubut' which hydraulic pressure is supplied by pneumaticpressure, such for instanceasJair-or steam. The advantage of such alsystem of actuation is that better controlthe movement of the car body can be attained' with a hydraulic motor than where the-,motor is actuated directly by the steamv or air, it being possible with'such a motor to control the speed by regulating the exhaust discharge while pressure is being ap-' Elied on the-supply side to move the car iody. By the hydro-pneumatic system hereindescribed, steam or air pressure is caused to act upon a body of oil or other liquid'in a suitable reservoir carried on the car, which liquid operates the motor on one side to move the [car body, and "its escape 3 "from. the other sidecontrols the movementof the car bodyduring its travel. a

A still further :lfeatureof improvement resides inthe provision of an actuating cylinder such that-twhile one side is receiving hydraulic pressure to move the car body,

the other side is acting as a'dash-pot coiiis a detail plan View; Figs. 3 and 4 are detailviews of modified actuating connections, and

Figs. 5 and 6 are details of the telescopicactuating cylinder.

The-car frame com rises the usual under "frame carried by en, bolsters 1, the under frame not'being herein shown, and it is supportedat the ends on vtrucks '23, which will 'not be particularly-described as these may be arranged according to particular necessities. The bolsters 1 each have'a stationary rack 2 and a track 3, and the car, body 4 is preferably secured to a bail 5 which is pro- 'vided with trunnions 6 at diametrical points. Rigidly secured to the trunnions 6 are gears 7 adapted to mesh with the racks 2 I (at each end of the car body) and rollers 8 which roll on the tracks 3the parts thus far described being of a well known construction.

In order to actuate the car body. there is mounted between the upright ends 10 of the bolster 1 a fixed plunger rod or guide rod 11, and at each end of this rod is a fixed cylinder 12, having respectively pipes 13. 14 for adr'nittingand exhausting the motor fluid therefrom. Telescoping within the cylinders 12*are cylinders 15, and similarly telescoping within the cylinders 15 are cylinders 16, these respective cylinders being su tably packed to prevent leakage; The cylinders 16 are each secured to a cross head 17 with which cross head actuating connection with the end of the trunnion 6 carried by the car body is made. As shown in Fig. 1, the cross head 17 is vertically slotted'at 18; and in this slot there is a crank pin 19 carried by a B 531 AVAILABLE CDPY crank 20, "Whieh"crank is adjustably se cured-to the trunnion 6."- As herein shown,

areI OVa'ble key 21 is inserted between the trunnion and the crank,- the crank having a second hole 22 so that when the key isr'e-- moved it may be shifted angularly when it isdesired to reverse the operationof the car body, as will be more fully explained.

Bythe provision .of telescopic. cylinders, in combination with the detachable connection permitting shitting otthe' cylinders independently ofthe car body for reversingthe operation of the car-body, the cylinders come wellwithin the lines of the car, forming a more compact" mechanism with better distribution of weights,- and also'permitting a greaterjmovement" of the motor, with consequently less exp I In order to'operate the motor by hydraulic pressure, a pair of tanks 24-, 25' are mounted on thecar body, each ofthese tanks being of a capacity to. somewhat exceed that of the total capacity of the telescopic cylinders 12, 15,- 16. The pipe 13 is connected with tank 24 and the pipe 14 with tank 25, and thesev tanks are each provided with to-and-froin pipes 26 which ar'econtrolled by a valve 27, the valve 27 being a four-way valve which admits air or steam pressure from pipe 28 to one of the tankswhile opening the other to the exhaust.

As willbe'seen from Fig. 1, the pipes '13 and14 lead respectively into the tanks 24:, 25 about mid-way of their height, and within each tank are extensions 29, 30 of the pipes'13, 1%, respectively hinged thereto and carrying floats 31, the purpose of these floats being to move 'the pipes 29, 30 as the fluid level in the tanks: varies. It is contemplated that these tanks will be filled. with oil, which. :will not freeze in cold weather, and to. apply pressure to the oil by meansot steam or air through the pipes 26, and-valve 27 As the to the cylinders.

vsteam condenses, the water thus formed will sink to the bottom'ot the oil so that by throwing the nozzles 29, 30 it is insured that oil and not water will always be transmitted In order to draw oil the water each tank is provided with a drain pipe 32 and pet cocks 33, as shown.- If air should be used instead of steam the floats and hinge joints can be eliminated. If, by reason 0t leakage the quantity-0f liquid in one tank ;should he insufiicient to fill the cylinder, liqu d can be'drawn from the other through pipe 32,

I which has a cock for this purpose.

'As shown in Fig. 1, the parts are in position to dump the car body .to the left, anr. the valve- 27 will-be thrown so as to connect the tank 25' with thesteam pressure, which will force the oil therein through pipes 30 and 1e into the right hand set of cylinders 1n 1:: 112 nmwnn- H10 nr-nqq lwnnrl 17 nr-tino' nditure of power to do the same amount of Work.

the oil which was already in the lefthand set of cylinders isforcedout through pipe 13 into tank 24, rising therein and forcing.

a the contained air out through pipe 26.

It will readily be seen that the speed of" the car body can be controlled as "desiredby restricting the discharge ofthe oil from the left hand cylinders through pipe 13, either by providing therein a hand valve as 35, or

freely to adfnit oil to the cylinders foractuating pressure and partiallyclosed when the oil is to be discharged for checking pressure 'an automatic check valve which will'open thus controlling the movement and actuatingthe car body bya single device. H

In Fig. 3, a, stationary cylinder is shown fin which the piston 36. lS-COIIIIEZOiZBd to a 'IHOVQblB PIStOH rod 37 which latter as con nected with the cross head 38 sliding one pair of fixed guides 39 carried byone of the end bolsters. The cross head 38 is forked at its upper end andbetweenthe partsis connected .a link 40 having a hole 41 with a. strap 42 which engages the trunnion 6.

In the position shown, the parts arein posi 40. .This brings the piston 36v at the left end of the stationary cylinder .12 and-upon adnnttmg pressure the piston Wlll move to the right 1n the same manner as before deri-ghththeupin" scribed. it will be understoodthat pipes 13 and will be connected to the tanks 25 111 the same manner'as before described,

or theymay be connected to some other source of actuating power, a s iswell i 1nder stood. In this case also, one side supplies power, while the other side controls the movement, 'or separate fixed cylinders and two pistons on a common movable rod could be used, acting similarly to Fig. 1L Byjthis" link construction, the power to tilt tlie car'.

body is .exerted directly across the axis of the trunnion 6 and by reason of the forked" cross head 38 and the'pi'n 43 there is less tendency to hending ofthe pin or shearing it as. e v i in Fig. t, the cross head 38 is connected with theftrnnnion ti; by niea'ns of an adjuse able crankQO similar to that before described, the crank being copnect'ed with fthe" forked cross head 38 by means of a link 40",- as before described. instead of the key 21' for locking om meme the crank-is provided with a his 4 5 ,1and the lendofi the trunnionis provided withv two notches set at an angular distance apart approximately equal to the tilting other formsbefore described, it will be ad--' 1'0 angle of the car body, and a clamp 46 thread'edinto the tru nnio'n locks the crank 111' one or the other of'the notches according.

to the direction in which the car body isto be" t1lted.- In this-form, as well as in the vantageous to use the hydro-pneumatic actui; ating system suchasshown in Fig. 1 though for actuating the piston and the cylinder,

as the case may be, may be provided. In theconstructions showing a crank-connection between the motor and the car body, it

will be seen that the .motorhas a greater travel than the car body, and this is advan tageous both because the applied power can thus act through a greater distance, and also the checking .force on the opposite side of the cylinder, whereby better contiiol'will be secured, with less strain on the parts From the foregoing description it will beseen that a dump car actuating mechanism is age or disarrangement'.

to secure by Letters Patent, is,

provided by this invention which will be simple in operation and not liable to break- Furthermore, by the use of the hydro-pneumatic actuating the car body can be effectually controlled and the actuating pressure supplied by steam or compressed air while at the same time a fluid check. is provided.

In case oil is used for transmitting the hydraulic pressure, the arrangement herein described for preventing the admission of water to the power cylinder is advantageous,

in that it'is insured that the water of condensation from the steam will be separated and not liable to enter the cylinder. Where the water is liable to freeze it is permitted totbe drawn off when a liasaccumulated. a V

lllodifications and changes in'the specific construction herein described can be made without departing from the scope 'o'fthe invention; asit will be seen that various forms of apparatuscan be devised which will "embody the principles of the invention.
